Question

the text states that regulatory t cells suppress t cells that mistakenly react against \self\ antigens. what is the most likely consequence if a persons regulatory t cells were unable to function properly? the immune system might attack the bodys own healthy cells, leading to an autoimmune disease. the cell - mediated response would never be able to activate, even when a pathogen is present. the person would be unable to form memory cells after an infection. virus - infected cells would not be destroyed effectively by cytotoxic t cells.

Explanation:

Regulatory T - cells prevent self - reactive T - cells from attacking the body's own cells. If they malfunction, self - reactive T - cells can attack healthy cells, which is characteristic of autoimmune diseases.

Answer:

The immune system might attack the body's own healthy cells, leading to an autoimmune disease.
